We establish that it is possible to extract accurate blockwise and bitwise soft output from
Guessing Codeword Decoding with minimal additional computational complexity by
considering it as a variant of Guessing Random Additive Noise Decoding. Blockwise soft
output can be used to control decoding misdetection rate while bitwise soft output results in
a soft-input soft-output decoder that can be used for efficient iterative decoding of long, high
redundancy codes.
